- Objective: To determine if levels of mannose-binding lectin (MBL) predict sepsis development and if intra-individual changes in circulating levels from baseline to the acute septic phase associate with in-hospital mortality.Method: A nested case-referent study within the framework of the Northern Sweden Health and Disease Study (NSHDS) and the Northern Sweden Maternity Cohort (NSMC). Patients aged 18 years or more with documented sepsis within 24 hours after admission to the intensive care unit were included if they had participated in a health survey and donated blood samples prior to the sepsis event. A subset of these patients had stored plasma also from the acute phase. Two matched referents free of known sepsis were selected for each case. Baseline and acute phase plasma MBL levels were determined. The association between MBL and sepsis, sepsis severity and in-hospital mortality were determined.Results: We identified 57 men and 95 women with a first-time sepsis event 6.5 years (median with IQR 7.7) after participation in a health survey, of which 127 also had samples from the acute septic phase. High baseline levels predicted future sepsis (OR 1.81, 95% CI 1.01-3.26), but were not associated with severity of sepsis or in-hospital fatality. Both high MBL levels in the acute phase (OR 4.94, 95% CI 1.44-16.89), and an increase from base line to the acute phase (OR 3.67, 95% CI 1.19-11.28) were associated with increased risk for in-hospital death in women, but not in men (OR 0.71, 95% CI 0.18-2.88). Low levels at baseline were not associated with future sepsis. Neither low levels at baseline, nor in the acute phase were associated with sepsis severity or in-hospital mortality.Conclusions: High pre-sepsis levels predicted a future sepsis event, and an increase from baseline to the acute phase as well as high levels in the acute phase associated with an unfavourable outcome in women.
